Question 30

Deifne COULOMB

Answer 30

Coulomb (C): A unit of electrical charge equal to 6.24 × 1018 electrons (or 6.24 quintillion electrons). A coulomb is the common unit of quantity used for specifying the size of a given charge.

Question 31

how doe batteries work

Answer 31

By covert stored chemical energy into electrical energy with Cathode (+) which are positive , and Anode (-) which are negative

Question 32

how Cathode and Anode work together

Answer 32

A battery chemically creates a large reserve of free electrons at the anode (-) terminal. The cathode (+) terminal has electrons chemically removed and will therefore accept electrons if an external path is provided via a circuit. When a battery is no longer able to chemically deposit electrons at the anode terminal, it is said to be dead, or in need of recharging.

Answer 52

voltmeter can be used to determine whether the correct voltage is available. A voltmeter must be connected in parallel with the component or circuit to be tested (Figure 33). Voltage must be checked with the power applied.

Question 53

Ohmmeter

Answer 53

An ohmmeter contains an internal battery that acts as a voltage source. Therefore, you must always make resistance measurements with the system power off. Sometimes, you use an ohmmeter to measure resistance in a load. Motor windings are a good example. Usually, you use an ohmmeter to check for circuit continuity. Continuity means that the circuit is continuous, with no breaks in the wire.
