The instrument used to measure current is called ampere meter or ammeter.
� | Steps for current measurement Connect a small light bulb to a dry cell. Measure current that passes through light bulb by connecting positive terminal (+) of ammeter to negative terminal (-) of a dry cell (see figure) | ||
� | Safety instructions for current measurement; | ||
1. | Estimate current that required measuring then choose a suitable ammeter, since each ammeter has different limit of current measurement. | ||
2. | Be sure that the connection to positive terminal (+) and negative terminal (-) of ammeter are correct. | ||
3. | Do not directly connect ammeter terminals to dry cell terminals. Since it can damage the meter. |
