Cfesa electric | UPDATED Questions with 100% Verified
Answers
Q1: Voltage
A: Potential difference or driving force of electrons
between two lines
Q2: Current
A: Measured in amps. Movement of electrons
through a circuit when a difference of potential
exists.
Q3: Direct current (DC)
A: Circuit electrons flow in only one direction from
negative to positive.
Q4: Frequency
A: (Hertz) number of times the alternating current
changes from 0 to its peak positive then zero to
peak negative then back to zero.
Q5: Power
A: Amount of energy used. Determined by voltage,
current, and resistance in a circuit.
Q6: Resistance
A: Impedance or opposition to the flow of current.
Measured in Ohms. Every circuit must have
resistance.
Q7: Circuit
A: a path for an electrical current to flow around
Q8: Series circuit
A: An electric circuit with a single path. (Castle
wall)
Q9: Parallel circuit
A: A circuit that contains more than one path for
current flow. (Parachute)
