Three resistors of resistance 15 , 25 , and 35  are connected in parallel with a 4 v battery. what is the current through each resistor?

If the resistance is 15: I = V / R I = 4/15 I = 0.27 The current is 0.27 amps (approximately).

If the resistance is 25: I = V/R I = 4/25 I = 0.16 The current is 0.16 amps.

If the resistance is 35: I = V/R I = 4/35 I = 0.1142 The current is 0.1142 amps (approximately).
