Question

when a 12v batery is connected across an unknown resistor,there is a current of 2.5 ma in the circuit.Find the value of resistance of the resistor

Answer 1

V ≈  12v

I ≈ 2.5mA  ≈  2.5×10 raised to -3

According to ohm's law V ≈ IR

⇒ R ≈ V/I

   R ≈ 12/2.5×10 raised to -3

  R  ≈ 4.8 × 10³ohms

According to Ohm’s law,

V = IR

=v/I

Here, V = 12 V and I = 2.5 mA = 0.0025 A Therefore,

=12/ 0.0025 = 4800 Ω = 4.8 kΩ

I hope, this will help you___❤❤

Thank you
