What unit is electric current measured in?
Think about how we measure 'flow' in an electric circuit.
Name one common insulator.
Consider what materials are used to cover wires.
What is the unit of current?
Think about how we measure electric flow.
True or False: A voltmeter must be connected in series.
Consider how you would measure voltage across multiple points.
A circuit contains a battery of 12 volts and a resistor that allows 3 amperes of current to flow. Calculate the resistance in the circuit.
Remember the relationship between voltage, current, and resistance.
If two resistors are connected in series with a total voltage of 10V and the first resistor has a voltage drop of 4V, what is the voltage drop across the second resistor?
Think about how voltage divides in series circuits.
