If you are referring to voltage drops in a series a.c. circuit, then you simply multiply the current through each impedance by the value of the individual impedances.
leading the voltage.
An RL circuit is a circuit containing resistance (R) and an inductance (L).
because of the reactances in the circuit
The voltage is greater than the applied voltage, why?
For a d.c. circuit, you divide its supply voltage by the resistance of its load. For an a.c. circuit, you divide its supply voltage by the impedance of its load.
the sum of the two
To figure out the amps in an electrical circuit, you can use Ohm's Law, which states that Amps Volts / Resistance. Measure the voltage across the circuit and the resistance of the components in the circuit, then divide the voltage by the resistance to calculate the amperage.
a form of low voltage DC to high voltage AC power conversion circuit.
Voltage will be constant. Resistance is dependent on the components in the circuit. Source: Electronics Technician for the US Govt
It depends on the circuit. For example, providing the a.c. voltage is the same as the rated d.c. voltage, it would not harm a lighting circuit.
Approx. 280 VRMS. Vpeak * 0.707 = Vrms
Voltage leads current or, more specifically current lags voltage, in an inductive circuit. This is because an inductor resists a change in current.
