Question

When a 12 v battery is connected to resistor,2 .5mA current flows through the circuit .if so what is the resistance of resistors

Answer 1

Answer:

this is answer of your questions

Answer 2

Given :-

Voltage of the battery = 12 V

Current of the battery = 2.5 mA

To Find :-

The resistance of the resistor.

Analysis :-

Substitute the given values in the formula of Ohm and find it accordingly.

Solution :-

We know that,

v = Voltage

r = Resistance

l = Current

Using Ohm's law,

$\underline{\boxed{\sf Voltage=Current \times Resistance}}$

Given that,

Voltage (v)= 12 V

Current (l) = 2.5 mA

Substituting their values,

12 = 2.5 × 10 R

R = 4.8 × 10³  Ω = 4800 Ω

Therefore, resistance of the resistor is 4.8 × 10³  Ω.
