WebTo find: Current (I) flowing in the circuit. Given: V = 20V, R = 4Ω Using Current formula I = V/R I = 20/4 I = 5 Answer: Current flowing in the circuit is 5 Ampere. Example 2: The total current flowing in an electric circuit is 50Amp whereas the resistance of the wires is 14Ohm. Using the current formula find the potential difference. Solution: WebThe electric charge is measured with the unit of Coulomb [C]. One coulomb has the charge of 6.242×10 18 electrons: 1C = 6.242×10 18 e. Electric charge calculation. When electric current flows for a specified time, we can calculate the charge: Constant current. Q = I ⋅ t. Q is the electric charge, measured in coulombs [C].
WebIf rate of flow of charge is not constant then the current at any instant is given by the differential limit: I = dQ/dt. If a charge Q flows through the circuit for time t, then I = Q/t. … WebFeb 22, 2024 · If amount of charge passing through the area every second remains constant, then Δ q is constant so the current is constant. If the charge flow varies with time, then we can define the instantaneous current by taking the limit as Δ t → 0 to get: i = d q d t
