If the resistance in a circuit connected to a constant current is halved, how is the voltage in the circuit affected?.

Sagot :

Answer:

Voltage will be 1/2 original

Explanation:

V = I R        if  I  is constant

V = k R       now multiply both sides by  1/2

1/2 V  = k 1/2 R     <===== you can see the voltage is halved too
