When 12 V battery is connected across an unknown resistor, there is a current of 2.5 mts in the circuit. Find the value of the resistance of the resistor. |
|
Answer» V = 12V, I = 25 mA = 25 × 10-3A, R = ? ∴ R = \(\frac{V}{I}\)[By Ohm's law] = \(\frac{12}{2.5\times10^{-3}}\) = 4.8 x 103Ω ∴ The value of the resistance of the resistor is 4.8 × 103 Ω. |
