A direct current (DC) solenoid valve in an industrial pneumatic system has an internal coil resistance of $15\text{ }\Omega$ . When connected to a $30\text{ V}$ DC power supply, what is the current flowing through the solenoid coil in amperes ( $\text{A}$ )?

Cevap: 2 A

Cevap

The current flowing through the solenoid coil is

2\text{ A}

According to Ohm's law, electrical current (

I

) equals voltage (

V

) divided by resistance (

R

). Substituting the given values yields

I = \frac{30\text{ V}}{15\text{ }\Omega} = 2\text{ A}

Adım Adım Çözüm

Identify the given circuit parameters

Voltage

V = 30\text{ V}

, Resistance

R = 15\text{ }\Omega

Extract the given values to identify which Ohm's law formula variation is required.

State Ohm's law formula for current

I = \frac{V}{R}

Current is directly proportional to applied voltage and inversely proportional to total circuit resistance.

Substitute the values and evaluate

I = \frac{30\text{ V}}{15\text{ }\Omega} = 2\text{ A}

Dividing

30

15

yields the circuit current in amperes.
