Two identical resistors are connected in series to a 12.0 V battery. The total resistance of the circuit is 16 $\Omega .$ (a) Calculate the voltage drop across each resistor. (b) Calculate the current through each resistor.

A DC circuit is formed by a 12 V battery and a 5-ohm resistor. Find the current Ir flowing through the resistor. Express your answer to 3 significant figures and include the appropriate unit.

You have been handed an unknown battery. Using your multimeter, you determine that when a $5.00-\Omega$ resistor is connected across the battery's terminals, the current in the battery is $0.500 \text{~A}$. When this resistor is replaced by an $11.0-\Omega$ resistor, the current drops to $0.250 \text{~A}$. From those data, find $(b)$ internal resistance of the battery.

a) In the given circuit, the thermistor has a resistance of $200 \Omega$.

i) Calculate the current through the resistor and thermistor.

ii) Calculate the potential difference across the $1000 \Omega$ resistor.

b) The temperature of the thermistor decreases so that the potential difference across the $1000 \Omega$ resistor becomes $4 \mathrm{~V}$. Calculate the new value of the resistance of the thermistor.

What is meant by the maximum working voltage rating of a resistor?

Two identical resistors are connected in parallel across a 25-V battery, which supplies them with a total power of 9.6 W. While the battery is still connected, one of the resistors is heated so that its resistance doubles. The resistance of the other resistor remains unchanged. Find

the initial resistance of each resistor

Determine the value of the resistor shown in Figure 3–62 for limiting the LED current to 20 mA and use the next higher standard value. Also specify the power rating of the limiting resistor.

A 12.0-V battery is attached to a 2.00-mF capacitor and a 100.- $\Omega$ resistor. Once the capacitor is fully charged, what is the energy stored in it? What is the energy dissipated as heat by the resistor as the capacitor is charging?

Which one gives off more power (as joule heating) when connected across the terminals of a 12-V battery: a $5.0-\Omega$ resistor or a $10-\Omega$ resistor? Explain your reasoning.
