CETa Study Guide Questions and Answers Rated A+ What is voltage, and why is it important in an electrical circuit? Voltage is the measure of electrical potential difference between two points. It is essential because it drives the flow of current through a circuit. What does frequency indicate in an AC circuit? Frequency indicates how often the current changes direction in an AC circuit, typically measured in hertz (Hz), which impacts how electrical devices operate. How does en...

Residential wiring final exam questions and answers 100% pass How does the layout of a room influence the placement of electrical outlets? The layout influences outlet placement by considering the furniture arrangement and functionality, ensuring accessibility while minimizing the risk of tripping hazards. What role does a grounding system play in residential wiring? A grounding system provides a safe path for excess electrical current to flow into the earth, reducing the risk of sh...

Rheobase - the lowest point on a strength duration curve at an infinitely long pulse duration Chronaxie time - the pulse width at twice the rheobase value. It approximates the most efficient stimulation pulse duration Charge (formula) - Charge= I(current) x T(time) Furman's formula - Energy(microjoules)= I(current)xV(voltage)xT(pulse width) Ohms law formula - Voltage(electromotive force)= I(current/flow of electrons) x R(resistance to current flow in ohms) Functional Refractory P...
