Question | Answer |
Moving charge is called | current |
Charge is measured in | Coulombs |
Conventional current flows | From positive to negative round a circuit |
Charge can be moved round a circuit using | a cell |
More than one cell is called | battery |
The two types of charge are | positive and negative |
The charge carried by electrons is | negative |
Protons and some ions are charged | positively |
In a metal wire charge is carried by | free electrons |
The electrons drift in a wire when they experience | the electrical force from the cell |
The direction electrons move in a wire | opposite to conventional current |
A substance containing both free positive and negative charges is called an | electrolyte |
The coulomb is defined as | that charge passing a point when 1 Amp flows for 1 second |
The symbol for the quantity of current is | I |
The unit for current is | Ampere (A) |
The symbol for the quantity of Charge is | Q |
The unit for charge is | Coulomb (C) |
The equation linking charge and current | ΔQ=IxΔt |
If 200 C pass in 20 seconds the current is | 10A |
The charge on a single electron is | 1.6 x10-19C |
How many electrons are in 1C | 6.25x1018 |
