Circuit Analysis and Resistor Calculations

In this video, Chris from Math Meeting explains how to analyze a circuit to find the current through and voltage across each resistor. The tutorial covers simplifying circuits using series and parallel formulas, calculating total current, and determining current and voltage in both series and parallel resistors. Chris also provides contact information for additional help and tutoring services.

What is the first step in analyzing the given circuit?

• Calculate the total current

• Simplify the circuit to an equivalent circuit

• Identify the battery voltage

• Find the voltage across each resistor

Which formula is used for resistors in series?

• R1 * R2 * R3

• R1 + R2 + R3

• 1/R1 + 1/R2 + 1/R3

• R1/R2 + R2/R3

How do you calculate the total current in a circuit?

• Voltage divided by total resistance

• Current times resistance

• Voltage times resistance

What is the current through a resistor in series if the total current is 2 amps?

• It varies depending on the resistor

• It is equal to 2 amps

• It is double the total current

• It is half of the total current

How is the voltage across a resistor calculated?
