1. Solve and calculate the power dissipated in each resistor in the image being captured. (series-parallel circuit)
Note: Solve in complete solution and explain briefly.
2. Explain: In a circuit, if the resistance is left constant and the voltage is doubled (for example, from 3V to 6V), how does the current change? Does this conform to Ohm's law?
Choices:
I. The current will double. This does not conform to Ohm's law as the current is proportional to the voltage.
II. The current will get doubled. This conforms to Ohm's law as the current is proportional to the voltage.
III. The current will decrease by half. This does not conform to Ohm's law as the current is proportional to the voltage.
IV. The current will increase by half. This conforms to Ohm's law as the current is proportional to the voltage.
