Question

11. In parallel combination of electrical appliance, total electrical power is *​

Answer 1

Answer:

in parallel combination of electrical appliances, total power consumption is equal to the sum of the powers of the individual appliances.

Answer 2

Total electrical power is:

Explanation:

• In equal mix of electrical apparatuses, absolute power blend is equivalent to the amount of the powers of the individual appliances.Consider electrical machines of abilities, $P_1,\ P_2,\ P_3$ having protections $R_1,\ R_2,\ R_3$ associated in equal. Presently, assume that they are worked at primary voltage $V$. Allow $P$ to be the complete power and $R$ be the all out obstruction of the blend of every electrical machine.
• Then as indicated by the law of opposition in equal
• $\frac {1}{R}=\frac {1}{R_1}+\frac {1}{R_2}+\frac {1}{R_3}$
• Duplicating both side by $V^2$ we get-
• $\frac {V^2}{R}=\frac {V^2}{R_1}+\frac {V^2}{R_2}+\frac {V^2}{R_3}$
• Or then again,
• $P=P_1+P_2+P_3$ $[\because \frac {V^2}{R}=P]$
• Thus, in an equal blend of electrical machines, all out power mix is equivalent to the amount of the powers of the singular apparatuses.
