The power in an electrical circuit is given by the equation p= rr, where /is the current flowing through the circuit and ris the resistance of the circuit. what is the current in a circuit that has a resistance of 30 ohms and a power of 2 watts? a. 15 amps b. 0.26 amps c. 3.9 amps d. 0.067 amps

B

Explanation:

P = I² R

If P is 2 watts and R is 30 ohms:

2 = I² (30)

I = √(1/15)

I ≈ 0.26 A

object 2 because all the other ones are wrong

one person pulls 90n one way and the other has 100n pulling the other way.

so the net force = 90 - 100 = -10n,

or the ans can be 10n if the picture shows -90n and 100n instead.
