Question

Use the formula V = IR to work out V when a) I = 4 and R = 9​

Answer 1

To work out V (voltage), you can use the formula V = IR, where I represents the current and R represents the resistance.

Given that I = 4 and R = 9, you can substitute these values into the formula:

V = (4) * (9)
V = 36

Therefore, when I = 4 and R = 9, the voltage (V) would be 36.
