Question

Напряжение в цепи 1,5 кВ, сила тока равняется 50 мА. Чему равняется сопротивление? Записать только число в кОм.

Answer 1

Ответ:

30

Объяснение:

R=U/I=1500 В / 0,05 А = 30000 Ом=30 кОм

Answer 2

Ответ: 30кОм

Объяснение:

Дано:

U=1,5кВ=1500В

I=50мА=0,05А

----------------------

R-?

R=U/I=1500/0,05=30000 Ом=30кОм

Answer 3

Calculation of Resistance

To calculate the resistance in the circuit, we can use Ohm's Law, which states that resistance (R) is equal to voltage (V) divided by current (I).

Given: - Voltage (V) = 1.5 kV (kilovolts) - Current (I) = 50 mA (milliamperes)

To find the resistance, we need to convert the voltage to volts and the current to amperes.

Converting the voltage from kilovolts to volts: 1.5 kV = 1.5 * 1000 V = 1500 V

Converting the current from milliamperes to amperes: 50 mA = 50 * 0.001 A = 0.05 A

Now we can calculate the resistance using Ohm's Law:

Resistance (R) = Voltage (V) / Current (I)

R = 1500 V / 0.05 A = 30000 ohms

Therefore, the resistance in the circuit is 30,000 ohms, or 30 kΩ.
