Current and Circuit Electricity 0.0 / 5 ? PhysicsElectricityIGCSEAQA Created by: Luci_Created on: 03-03-17 19:39 What is an electrical current? A flow of charge 1 of 11 In a series circuit does the current stay the same or split? It stays the same 2 of 11 I = Q/t - What does the I stand for and what are the units? I = Current 3 of 11 What is the unit of charge (Q) Coulomb (C) 4 of 11 What is another word for Voltage (V) Potential difference 5 of 11 V = E/Q - What does the E stand for and what are the units? Energy (J) 6 of 11 Potential difference is transferred by what? per unit charge 7 of 11 In a series circuit is potential difference shared or constant? Shared V1 = V2 + V3 8 of 11 What does resistance measure? How hard it is for a current to flow 9 of 11 V = IR - What does the V stand for and what are the units? Voltage (V) 10 of 11 What does Ohms law state? If resistance is constant, current is directly proportional to potential difference. 11 of 11
