SUMMARY

The discussion focuses on calculating the current through two resistors, R1 (1755 ohms) and R2 (4020 ohms), connected in parallel with a battery emf of 15 V. The voltage across each resistor is equal to the applied voltage of 15 V. Using Ohm's Law (I = V/R), the current through R1 is calculated as I1 = 15 V / 1755 ohms, and the current through R2 is calculated as I2 = 15 V / 4020 ohms. This method provides a clear approach to finding the current in parallel resistor circuits.

PREREQUISITES
  • Understanding of Ohm's Law (I = V/R)
  • Knowledge of parallel resistor circuits

Homework Statement


Two resistors with R1 = 1755 omega and R2 = 4020 omega are connected in parallel. The battery emf is large epsilon = 15 V.

What is the current through resistors R1?
What is the current through resistors R2?


Homework Equations





The Attempt at a Solution


I know I am somehow supposed to use V=Emf - Iresistance, but i don't feel like i have enough information. Do i just need to somehow find V and then plug it in? If so what formula do i use?

In the parallel combination of the resistances, voltage across each resistance is same and is equal to the applied voltage. Use ohm's law to find the current in each resistance.
