DC Fundamentals Unit 7 – Series Resistive Circuits
Exercise 2 – Current in a Series Resistive Circuit ....................................................................
EXERCISE OBJECTIVE
When you have completed this exercise, you will be able to determine the current flow in a series
resistive circuit by using a formula. You will verify your results with a multimeter.
EXERCISE DISCUSSION
- Electric current is the flow of electrons between two points in a circuit.
- In a series circuit, there is only one current path; therefore, the same current flows through
each resistor. - Current flowing through a resistor generates a voltage drop across the resistor.
- When the voltage drop across a resistor is known, Ohm’s law can be used to determine total
current in a series circuit.
