Two ammeters $A_1$ and $A_2$ are connected as shown in the given figure. By neglecting the internal resistance of the ammeters, the reading in the meter $A_1$ is (in $\text{A}$)

What is the current through an ideal $PN-$ junction diode shown in the figure below? (in $mA$)

The current-voltage relation of a diode is given by $I = \left( {{e^{\frac{{1000V}}{T}}} - 1} \right) \, mA$,where the applied voltage $V$ is in volts and the temperature $T$ is in Kelvin. If a student makes an error of $\pm 0.01 \, V$ while measuring the voltage to obtain a current of $5 \, mA$ at $300 \, K$,then the error in the value of the current in $mA$ is.....$mA$

What is a diode?

The current through an ideal $PN-$ junction diode shown in the following circuit diagram will be.......$mA$.

The current-voltage relation of a diode is given by $I = (e^{1000V/T} - 1) \; mA$,where the applied voltage $V$ is in volts and the temperature $T$ is in Kelvin. If a student makes an error of $\pm 0.01 \; V$ while measuring the voltage to obtain a current of $5 \; mA$ at $300 \; K$,what will be the error in the value of the current in $mA$?
