V=i*r

18-15=3*r

r=3/3=1 ohm

How do you convert peak voltage to peak-peak voltage?

Simply multiply the peak voltage to 2 and you will get the peak to peak voltage.

What is the maximum DC voltage you could expect to obtain from a transformer with an 18V rms secondary using a bridge rectifier circuit with a filter capacitor?

The maximum DC voltage you could expect to obtain from a transformer with an 18V rms secondary using a bridge rectifier circuit with a filter capacitor is about 24V.This assumes a truly sinusoidal AC waveform, and a forward conductioin voltage of 0.7 volts across each diode.Multiply 18 by the square root of two, and subtract two times the diode voltage.The maximum is the peak value. If there is any load on the output, there will be some ripple, but the peak value will still be around 24V.To calculate the output voltage of single phase diode bridge it is reasonable to assume a filter capacitor exists across the output and realize that it will be charged to the maximum voltage available to it.

How do you draw 18V current from 24V d.c battery?

You are confusing terms. Current is measured in amps or some fraction thereof. If you have a 24 volt battery (All batteries are DC) you need to connect a load to the battery and then measure the current that flows in the circuit. The current is measured in amps, milliamps or perhaps microamps for a very high resistance load.

What items are in the Black & Decker 18V 4 Tool Combo Kit?

This kit includes an 18V 2 speed drill/driver, 18V 7-1/4" circular saw, 18V reciprocating saw, 18V cordless flashlight, 2-18V batteries,and a charger.

What is the equivalent in horsepower of 18 volts?

The question doesn't make sense. 18V is a measure of potential difference while horsepower is a measure of power. If you find out the current, then you can calculate the power and compare the two quantities. Power (in watts) = Voltage (in volts) * Current (in amps) and 1 hp = 746 Watts so 18V * current (in amps) / 746 = power in horsepower. (this assumes the 18V is DC)

Three cells have voltage of 15V 18V and 20 V What is the total voltage of the cells when they are connected in parallel?

Sources with different voltages should never be connected in parallel, you would have a difference of potential. Any time you have a difference of potential connected together you will have sparks, which could cause the batteries to explode.

How much current will flow in a simple series circuit with a voltage drop of 10 volts and another voltage drop of 8 volts and a total resistance of 2 ohms?

V=R I then, V = 10 + 8 = 18V, R=2Ohm, I=V/R=18/2=9A

How many amps is 20v dc 18v ac 35va dc max?

To convert VA to amps for DC, you can use the formula: Amps = VA / Volts. For the given values, the max DC current would be 35VA / 20V = 1.75A. The 18V AC value cannot be directly converted to amps without additional information.
