Problem 4 (20 points): The power absorbed by an element is equal to the product of the voltage across it and the current passing through it (in the direction from high to low potential), i. e. P = V × . For a resistor, this value is always positive (implying that the resistor "absorbs" power). The value will be negative if an element "delivers" power (which is usually but not always the case for a power source). In the following circuits, state whether the 5V power source is "absorbing power from" or "delivering power to" the circuit. Find this power.
