Why resistor should disconnected from the circuit when measured the value of resistor?

if not disconnected you will measure the resistance of the circuit in parallel with the resistor.


What is the relation between the size of the resistor and its value?

There is no relation between the resistor's ohms value and its size. The power of the resistor can be seen by its size. If the power is too small, the resistor can be destroyed.


A 5 ohm resistor a 10 ohm resistor and a 15 ohm resistor are connected in series to a 120 volt power source. What is the amount of current flowing between the 5 ohm resistor and the 10 ohm resistor?

The current would be about 20 volts.


Define zero ohm resistor.?

A zero-ohm resistor does not exist, so we are talking about an ideal resistor. An ideal resistor is needed for description in a circuit, where we lump all wire/parasitic resistances into discrete resistors, but the wire joining two discrete resistors is considered to have no resistance. My definition: a zero-ohm resistor is an ideal resistor that does not consume energy when a current exists in the resistor. Alternatively, a zero-ohm resistor is an ideal resistor that cannot sustain any potential drop when a current is on. Thirdly, a zero-ohm resistor is an ideal resistor that will conduct an infinite current when a voltage is applied across it.


2 resistors unequal value are in parallel. Would the power dissipated by the resistor with larger ohmic value be greater than the power dissipated by the resistor of lesser value?

No, because the power dissipated in a resistor is proportional to the square of the current through the resistor but only directly proportional to the resistance of the resistor (I^2 * R) and the current through the lower value resistor will be higher than the current through the higher value resistor, the lower value resistor will usually dissipate more power.

Is stepped a intransitive?

"Stepped" is typically a transitive verb, as it usually requires an object to complete its meaning. However, in certain contexts, "stepped" can also be used intransitively when the object is implied or understood from the context. For example, "He stepped into the room" is transitive, while "He stepped carefully" is intransitive.
