In this interactive object, learners solve for total resistance and current, the current through each resistor, the voltage across each resistor, and the power dissipated by each resistor.

The learner will calculate basic circuit resistance.

Learners study animations to see the connection between temperature and resistance as they examine the operation of an RTD. A table is used to convert resistance readings to the corresponding temperatures. A brief quiz completes the activity.

Learners follow a methodical approach for the dc analysis of series-parallel circuits.

Students view a sample of the keystrokes of a TI-30XIIS calculator that are required to solve for the instantaneous current of a de-energizing circuit.

Students view a sample of the keystrokes used on a TI-36X calculator to solve for the instantaneous current of a de-energizing circuit.

Learners view a sample of the keystrokes on a TI-36X calculator that are required to solve for the instantaneous current of an energizing RL circuit.

Learners calculate the total cost of a loan by entering the principal amount, the period of the loan, and the annual percentage rate.
