Question

What is the resistance in a circuit that has a current of 0.75A and a voltage drop of 60V across the cell?( Please help) I will give brainliest

Answer 1

Answer:

80

Explanation:

Voltage= current * resistance

V= IR

Remember I= current and the unit of current is amps= A

Answer 2

difference across the 12.0 Ω resistor is 1.20 V, calculate the emf of the cell. 45. Req = 13.5 Ω ... (b) I = V / Reff = 1.5 / 2 = 0.75 A.
