Question

NEED HELP QUICKLY....A 9.0Ω resistor is connected in series with another resistor and a 6.0 V battery. The current in the circuit is 0.60 amps. Calculate the resistance of the unknown resistor. 9.0Ω 8.0Ω 5.0Ω 1.0Ω

Answer 1

Answer:

= 1.0 Ω

Explanation:

Total resistance of resistors is calculated by adding the resistance of each resistor.

In this case, one resistor is 9.0Ω and lets assume the other has R Ω

Therefore; Total resistance is = (9 + R) Ω

From the Ohm's law; R = V/I

Thus;

(9 + R) = 6.0/0.60

9 + R = 10

R = 1 Ω

Therefore, the resistance of the unknown resistor is 1.0 Ω
