Question

the potential difference between the yellow wire and the black wire (which is attached to "ground" or zero volts) is about 4.73 volts. If the voltage across the 330 ohm resistor is 2.53 volts, then what is the value (in milliamps, where 1 milliamp = 0.001 amps) of the electric current through the resistor

Answer 1

The electric current through the resistor is: 7.66667 milliamps

Step-by-step explanation:

Applying Ohm's law we have
`V = I * R` or solving to
`I = (V)/(R)` so now, we can replace the values given before in the equation, we need to know that the voltage across the resistor is which determine the current in the component, in this case, the resistor. After clear this topic, we get
`I = (2.53 (volt))/(330 (ohms)) = 0.00766667 (ampers)` so 1 milliamps is 0,001 amps we get 7,66667 milliamps.
