Vedclass · Answer

(A) The current $I$ drawn by a person is given by Ohm's Law,$I = V/R$,where $V$ is the potential difference across the body and $R$ is the resistance of the body.In option $(B)$,the person is standing on a wooden plank (an insulator),so they are isolated from the ground. When they touch the Van de Graaff generator,their entire body reaches the potential of $12000 \,V$. Since there is no potential difference across their body,the current $I = 0$.In option $(A)$,the person touches the live $(220 \,V)$ and neutral $(0 \,V)$ terminals. The potential difference is $220 \,V$,which drives a significant current through the body.In option $(C)$,the potential difference is $12 \,V$.In option $(D)$,the total potential difference is $10 	imes 1.5 \,V = 15 \,V$.Comparing the potential differences,the $220 \,V$ source provides the highest potential difference,resulting in the maximum current.

In the scenarios given below,a person is standing on a wooden plank. In which of the following options do they draw the most current when simultaneously touching:

The reading of the ammeter in the adjoining figure will be .............. $A$.

The potential difference $V_B - V_A$ in the network shown is ............. $V$.

In the given circuit, the current flowing through the resistance $20 \, \Omega$ is $0.3 \, A$, while the ammeter reads $0.8 \, A$. What is the value of $R_1$ in $\Omega$?

In the circuit,$R_{1} = R_{2} = R$. The value of $E$ and $R_{1}$ are $\ldots \ldots \ldots$ ($E$ = $EMF$,$R_{1}$ = resistance).

Two resistances $R_1$ and $R_2$ are made of different materials. The temperature coefficient of the material of $R_1$ is $\alpha$ and of the material of $R_2$ is $-\beta$. The resistance of the series combination of $R_1$ and $R_2$ will not change with temperature,if $R_1/R_2$ equals
