 1
Three resistors are wired in series. R1=220 ohms, R2=660 ohms, and R3= ohms. What is the total resistance of this circuit in ohms?

 2
Two resistors R1=480 ohms and R2=220 ohms are wired in a series and connected to a volt power supply. How many amps will flow through the battery?

 3
If two resistors R1=480 ohms and R2=220 ohms are wired in a series with a volt power supply, how many amps will flow through R1?

 4
Two resistors are wired in a series. R1=220 ohms and R2=660 ohms. A battery provides volts to the circuit. If a voltmeter is used to measure the voltage across R1, how many volts should it read?

 5
A resistor of 470 ohms is connected to a volt battery. How much power (in watts) will it use?
