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

Answer:

d. 12A and 18 V

Explanation:

first u have to find potential difference that is V. by formula V = IR

than u have to find power by formula P= VI.
