Ac Through Resistor Class 12. Sachin sir physicsin this video i have explained a c voltage applied to resistance r mm s valueinsta sachin sir physicsfacebooksachin upadhyayhttps drive g. Class 12 physics alternating current.
We have a resistor and an ac voltage v represented by the symbol that produces a potential difference across its terminals that varies sinusoidally. Input ac voltage v v m sinωt equation 1 where v m peak value of voltage. In this section we will deal with an electric circuit where an ac voltage is applied across a resistor.
A phasor is a rotating vector having the following properties.
Let us consider the circuit shown below. Class 12 physics alternating current. Let vr and vc be the potential drop across r and c respectively. Resistance is the opposition to the flow of current.
