Resistors can be installed in any direction in a circuit. It doesn't matter in which direction you are installing a resistor. Resistor will resist the current in both sides of the connection. You can also apply capacitor in any direction for alternating current. Where as if you are concerned with direct current, a direction is needed to apply the connection

Does it matter which way a emitter resistor is installed?

A resistor is not polarity sensitive, and may be installed in either direction. That's why resistors don't have pluses ( + ) or minuses ( - ) printed on them.


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.

How do you use resistor in a sentence?

I installed a resistor inline with my oil pressure sensor. The resistor in a circuit will usually disperse energy as heat.

Sure, if you try hard enough...


Why reduce voltage from a ignition coil by putting a resistor in the spark plug?

Sometimes a resistor is installed in spark plug wire as a supressor to reduce radio static interference
