Question

Який опір обмотки паяльника, якщо при напрузі 127 В сила струму в ній 500 мА?

Answer 1

Ответ:

Объяснение:

R = U / I= 127 / 0,500 ≈ 254 Ом

Answer 2

Calculating the Resistance of the Soldering Iron Coil

To calculate the resistance of the soldering iron coil, we can use Ohm's law, which states that the resistance (R) in a circuit is equal to the voltage (V) divided by the current (I). The formula for Ohm's law is:

R = V / I

Where: - R = resistance in ohms (Ω) - V = voltage in volts (V) - I = current in amperes (A)

Given: - Voltage (V) = 127 V - Current (I) = 500 mA = 0.5 A

We can now calculate the resistance using the provided values.

Calculation

Using the formula R = V / I, we can calculate the resistance:

R = 127 V / 0.5 A

R = 254 Ω

So, the resistance of the soldering iron coil is 254 ohms.

This calculation is based on the provided values and the application of Ohm's law for determining resistance in a circuit.
