I am adding 1 ohm resistor with a coil in series and an connecting to a 25 W DC source. How to choose the correct resistor of 1 ohm?

I am adding 1 ohm resistor with a coil in series and connecting to a 25 W DC source. How to choose the correct resistor of 1 ohm? Is 1 ohm, 25W resistor is OK for this circuit? Please help.

The supplied voltage is 5 volts and current in the circuit is 5 amps.

• Do you mean '25 V DC source'? Commented Jan 9, 2022 at 11:01
• Your question can't be answered because coil resistance and the voltage of the supply is required to calculate how much power is dissipated in the 1 ohm resistor. Commented Jan 9, 2022 at 11:02
• Since it is connected to the DC supply so coil's resistance is zero. The supplied voltage is 5 volts. and current in the circuit is 5 Amp. Commented Jan 9, 2022 at 11:06
• What kind of coil have you got that has a resistance of zero? Commented Jan 9, 2022 at 11:12
• @ShivamKumar I highly doubt your coil has zero resistance, unless it is a superconductor. Commented Jan 9, 2022 at 11:37
