The voltage across each resistor is the same: 120V
then, for each resistor Ri, the current is
Ii = 120/Ri amps
A 20.0-Ù resistor and a 45.0-Ù resistor in parallel are connected to a 120-V dc source.
(a) What is (are) the current(s) through the resistors?
current through the 20.0-Ù resistor:
Incorrect: Your answer is incorrect. .
A
current through the 45.0-Ù resistor:
Incorrect: Your answer is incorrect. .

(b) What is the voltage drop across each resistor?
voltage drop across the 20.0-Ù resistor:
Incorrect: Your answer is incorrect. .
V
voltage drop across the 45.0-Ù resistor:
Incorrect: Your answer is incorrect. .
V
