How do you bias a 2N5777 photo-transistor?
connect the base of the transistor to a variable resistor and to a normal resistor
How do you place 3 resistance to get the total resistance of 1 ohm?
It depends on the resistance of each resistor. If each resistor, for example, is 0.333 ohm, then you could connect them in series. If each resistor, for example, is 3 ohms, then you could connect them in parallel.
How to calculate the resistance to step down DC voltage?
Connect a variable resistance across DC source (fixed ends of variable resistor or Rheostat) and take decreased DC output across its one fixed terminal and other variable terminal of variable resistor. Other method is connect variable resistor in series with DC output and load, vary the resistance and take decreased DC voltage as required.
What is the purpose of a resistor in an electronic circuit If the resistor converts energy to heat then are you wasting energy any time you use a resistor?
In its simplest use a resistor in a circuit is used to limit the amount of current flow, or to decrease the amount of voltage applied to a device. One example is you had a 12 volt battery and you need/ wanted to connect it to a device that ran on 9 volts then a resistor can be chosen to reduce the 12 volts to the 9 volts required.
How do you connect and measure voltage using a voltmeter?
with a voltomiter
How connect a variable resistor to circuit?
To connect a variable resistor to a circuit, identify the two terminals of the variable resistor. Connect one terminal to the input or output of the circuit where you want to adjust the resistance. Connect the other terminal to either the ground or another reference point depending on the circuit's design. Ensure that the resistance value on the variable resistor is adjusted as needed for your circuit application.
How do you find amperes when using a resistor?
if you want to find the current (in amperes) through the resistor then connect a ammeter in series with the resistor.
Ism there 0 ohm resister available in market then its colour coding what?
Why would you buy something that does absolutely nothing? If you need a "zero ohm resistor", just don't connect any resistor at all.Why would you buy something that does absolutely nothing?

How do you install a resistor in an DC circuit?
It depends on the purpose for installing the resistor. If the intent is to decrease current flow, the resistor must be connected in series with the load. If the purpose is to increase current flow, the resistor must be connected in parallel with the load. To connect a resistor in series, connect the resistor to one side of the power source, in line with the load. This will decrease circuit current flow. To connect a resistor in parallel, connect the resistor between the positive and negative sides of the power source, which will effectively connect the resistor across the load . This will increase current flow through the circuit. However, before connecting a component in parallel, make sure the increase in current flow will not exceed the current rating of the circuit or fuses/breakers will blow.

How are you going to arrange a circuit if you want to measure the potential drop across a resistor?
Connect a power source to the resistor (+ve terminal to one side of the resistor and -ve terminal to the other) then connect a voltmeter in parallel with the resistor. The reading on the voltmeter will provide a measure of the potential difference across the resistor (ie: the voltage drop across it).
How do you connect resistance is series?
I'm going to take this as "How do you connect resistors is series?" just connect one wire of the first resistor to one wire of the second.
What are the 3 parts of every cicuit?
a power source, a resistor and wiring to connect them.
How do you connect in order to produce a maximum current in a given external resistor?
in parallel
How do you UNCHARGE a capacitor?
Connect it, in series, to a resistor or a dummy load and a switch. And then throw the switch.
Which resistor is connect 1.5 volt led to series 220v ac?
Typically, a 100 ohm resistor is used to connect a 1.5 volt led to a series 220v ac adapter. Many LEDs can be connected into a string using the resistors.
