Question

In the circuit show, there is current of 3A in the 2 ohm resistor, what are the values of
the current I delivered by and voltage across the power supply
a. 3A and 10v b. 4A and 9v
C. 4A and 12 v d. 12 A and 18 V​

Answer 1

Explanation:

When I = 3A and V = 10v

R = V/R

R = 10v/3A = 3.3ohm

When I = 4A and V = 9v

R = 9v/4A

R = 2.25ohm

When I = 4A and V = 12v

R = 12v/4A

R = 3ohm

When I = 12A and V = 18v

R = 18v/12A

R = 1.5ohm
