Where E is the electric energy, V is the voltage, and q is the amount of charge moved via voltage V in a time interval t which is equal to the integral of power over time. 2. What is Power in Terms of Physics? Can Power be Negative? Power is the measure of the rate at which ...
Ques. Calculate the electric power of the circuit whose current is 3 Ampere and voltage is given as 10 volts. Ans.Here,Current flowing in the circuit = I = 3 Amp Potential difference along the circuit = V = 10 volts By the formula of electric power, ...
Two Common Types of Voltage: Direct and Alternating Current There are two common ways of transferring electrical energy: direct current and alternating current. Direct current (DC) can increase or decrease in all sorts of ways, but the magnitude of the changes is usually small with re...
where P is the active power, U and I are the voltage and current respectively, and cosφcosφ is called the power factor. Therefore, the probability value of the current located in the interval [I1, I2) is as equal as that of the active power located in the interval [3−−√...
