Question

Найди сопротивление гальванометра, если через него протекает ток силой 10 мкА, а напряжение равно 5 мВ.

Answer 1

I=10 мкА=0,000010 А
U=5 мВ=0,005 В
I=U/R    
R=U/I=0.005/0,00001=500 Ом

Answer 2

Calculating the Resistance of the Galvanometer

To calculate the resistance of the galvanometer when a current of 10 µA flows through it and the voltage is 5 mV, we can use Ohm's law, which states that the resistance (R) is equal to the voltage (V) divided by the current (I).

Using Ohm's law: The resistance (R) can be calculated using the formula: R = V / I

Given: Current (I) = 10 µA = 10 * 10^-6 A Voltage (V) = 5 mV = 5 * 10^-3 V

Calculating the resistance: R = V / I R = (5 * 10^-3) / (10 * 10^-6) R = 500 Ω

So, the resistance of the galvanometer is 500 Ω.
