Which row correctly defines electric charge Q Q\,Q and states the direction of electron flow in an electrical circuit?
| Definition of charge QQQ | Direction of electron flow | |
|---|---|---|
| A | Q=It\displaystyle Q = \frac{I}{t}Q=tI | from negative terminal to positive terminal |
| B | Q=I×tQ = I \times tQ=I×t | from negative terminal to positive terminal |
| C | Q=I×tQ = I \times tQ=I×t | from positive terminal to negative terminal |
| D | Q=It\displaystyle Q = \frac{I}{t}Q=tI | from positive terminal to negative terminal |
