Insulation resistance - Study guides, Class notes & Summaries

ASE A6 Test Prep – Electrical/Electronic Systems - Questions, Answers and Explanations Adding an additional path through which the current can flow has decreased the total resistance of the circuit. Each light drops 12 volts. An ohmmeter is being used to check a circuit for continuity. Technician A says an infinity or full scale reading on an ohmmeter indicates no continuity. Technician B says a zero reading on an ohmmeter indicates continuity. Who is right? A. Technician A only B. Technician...

Electric Wiring Questions and Answers Already Passed What is the most common material used for the conductive part of electric wiring? Copper is the most common material used in electric wiring because it conducts electricity efficiently and is relatively affordable. Why is aluminum sometimes used in wiring instead of copper? Aluminum is lighter and cheaper than copper, making it a viable alternative, especially for overhead power lines. How does insulation play a crucial role in...

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...
