Question

Three resistors of 15 Ohm,20 Ohm ,25 Ohm are connecting series with a 12 V power

supply. Calculate their combined resistance, the current that flow in the circuit and in each

resistor and the potential difference across each resistor? please help fast and give a long answer​

Answer 1

Answer:

In series combination current through all the resistor is same

Potential drop across 15Ω resistor =3V

3=i×15⇒

i=
