show that the current and the voltage are in the phase with each other when ac is appiled to pure resistor
Answers
R is a resistive component, L is Inductive and C is Capacitive. and in a C component, the phase angle between the current and voltage vectors is +90 deg i.e. the current vector leads the voltage vector by 90 deg. Hope this is what you are looking for? The series RLC circuit resonates when Xl and Xc are equal.Nov 14, 2018
Ohm's law states that the electrical current (I) flowing in an circuit is proportional to the voltage (V) and inversely proportional to the resistance (R). Therefore, if the voltage is increased, the current will increase provided the resistance of the circuit does not change.
In a pure ohmic AC Resistance, the current and voltage are both “in-phase” as there is no phase difference between them. The current flowing through the resistance is directly proportional to the voltage across it with this linear relationship in an AC circuit being called Impedance.
Answer:
current and voltage phases change when inductor or capacitor present.
