Question

При каком сопротивление реостата сила тока будет равна 200А , а напряжение - 26 кВ

Answer 1

R =  U / I
26 кВ = 26.000 В
R = 26.000 / 500 = 260 / 5 = 52 Ом.
Ответ: 52 Ом.

Answer 2

Calculating Resistance for Given Current and Voltage

To calculate the resistance (R) required for a current (I) of 200A and a voltage (V) of 26kV, we can use Ohm's law, which states that resistance is equal to voltage divided by current (R = V/I).

Using the given values: - Current (I) = 200A - Voltage (V) = 26kV

We can calculate the resistance (R) using the formula R = V/I.

R = V/I R = 26,000V / 200A R = 130 ohms

So, the resistance required for a current of 200A and a voltage of 26kV is 130 ohms.
