A 4000 ohms resistors is connected across 220 volts. What current will flow?

Sagot :

Answer:

The current that will flow through the network is 0.055A or 55mA.

Explanation:

Ohm's Law states that the current is directly proportional to the voltage and inversely proportional to the resistance.

The formula use in Ohm's Law is:

[tex]V=IR[/tex]

where

[tex]V[/tex]     is the voltage, unit is in volts (V)

[tex]I[/tex]      is the current, unit is in amperes (A)

[tex]R[/tex]     is the resistance, unit is in ohms (Ω)

For the given information:

[tex]R=4000[/tex] Ω

[tex]V=220 volts[/tex]

Solving the problem:

Use the Ohm's Law formula, then substitute the given information, we get:

[tex]V=IR[/tex]

[tex]220V=I(4000[/tex]Ω[tex])[/tex]

Divide both sides by 4000Ω, we get:

[tex]I=\frac{220V}{4000 ohms}[/tex]

[tex]I=0.055A[/tex] or [tex]55mA[/tex]

Therefore, the current flowing through the network is 0.055A or 55mA
