Solving Electric Circuit: Magnitude & Direction of Resistor 1 & 2

Click For Summary
SUMMARY

This discussion focuses on solving electric circuits, specifically determining the magnitude and direction of current through resistors in a circuit. The key principles utilized include Kirchhoff's Voltage Law (KVL) and Ohm's Law (V=IR). The current through resistors in a series circuit remains constant, and the direction of current flow is from the positive to the negative terminal of the battery. Understanding these concepts is essential for accurately analyzing the circuit in question.

Hello everyone. This problem has me stumped.
The questioin asks,
" find the magnitude (current) and direction of both resistor 1 and resistor2"
(in the picture the top resistor is resistor 1)
I know [tex]V=IR[/tex], but I am stumped at how the different potentials interact with eachorther at resistor 2? Could someone please give me some guidance as to starting this?
Thanks so much
Chris

The picture isn't working, can you describe the circuit?
Are the resistors in series or parallel.
What is the source of EMF and how is it connected ( Series or parallel ).
 


Hi Chris,

Solving electric circuits can be a bit tricky, but with the right approach, it can become easier. In this case, you can start by analyzing the circuit and identifying the different elements and their connections.

Firstly, you can use Kirchhoff's voltage law (KVL) to determine the voltage across each resistor. KVL states that the sum of the voltage drops in a closed loop must equal the sum of the voltage sources in that loop. In this circuit, the voltage source is the battery, and the voltage drops are across the two resistors.

Next, you can use Ohm's law (V=IR) to calculate the current flowing through each resistor. Remember that the current is the same at any point in a series circuit, so the current through resistor 1 will be equal to the current through resistor 2.

To determine the direction of the current, you can use the convention that current flows from the positive terminal of the battery to the negative terminal. You can then follow the direction of the current through the circuit and determine the direction of current through each resistor.

I hope this helps you get started on solving the problem. Remember to always use the correct equations and follow the current flow direction convention to get accurate results. Good luck!
