Question

A 12 V battery has an internal resistance of 0.5?. a) What is the current through the 4? resistor? b) The temperature surrounding the circuit increases by 25°. If the temperature coefficient of the 4? resistor is 0.035 what is the current going through the resistor at this new temperature if The temperature change does not affect the battery?

Step 1

Ohm's Law states that the current (I) flowing through a resistor is equal to the voltage (V) across the resistor divided by the resistance (R) of the resistor. Mathematically, this can be written as: I = V / R In this case, the voltage across the resistor is 12V Show more…

A 12V battery has an internal resistance of 0.50 ohms. What is the current through the 4-ohm resistor? b) The temperature surrounding the circuit increases by 25 degrees Celsius. If the temperature coefficient of the 40-ohm resistor is 0.035, what is the current going through the resistor at this new temperature if the temperature change does not affect the battery?
