Cfesa electrical chapter 2
In a parallel circuit the total resistance of the circuit will always be less than what resistance. - The
smallest resistance
What happens to voltage in a parallel circuit? - Its the same across all components
What happens to voltage in a series circuit? - Voltage is shared between components
What happens to current in a series circuit? - The current is the same in all resistances
How do you find the total resistance in a parallel circuit? - Add the resistances together
How do you find the total resistance in a series circuit? - 1/rt= 1/r1 + 1/r2 + 1/r3
What happens to current in a parallel circuit? - Divides throughout each resistance
If a circuit is wired parallel, and the supply voltage is 120, each lead must be rated at what voltage? -
120v
If a circuit has two elements wires in series, and each is rated at 120v, what voltage must be supplied to
the circuit in order for he elements to heat at full power? - 240v
