Practice Problems

New Problems reloads the page with new variable values in all questions. You must do this after grading the test to rework it another time.
Make sure to enter your answers in the specified units .
Two resistors, R1= ohms and R2= ohms are connected in parallel to a 6.0 volt battery. What is the combined resistance of the circuit?

The current in the circuit will be how many amps?

If two identical resistors of ohms are wired in parallel to a 15 volt battery, how much current (in amps) will flow through the battery?

A 12 volt battery is connected to a resistor of ohms. How much current (in amps) will flow?

If the circuit in problem 4 operates for 25 seconds, how much power (in watts) will be dissipated in the resistor?

Once you have submitted your answers for grading by clicking the grade button, you cannot resubmit answers for the same Problem Set--you must use the 'New Problems' button first.
