What principle explains why charge is conserved in electrical circuits?
What principle explains why charge is conserved in electrical circuits?
The principle of conservation of charge states that the total electric charge in an isolated system remains constant over time.
When capacitors are connected in parallel, how is the total capacitance calculated?
When capacitors are connected in parallel, how is the total capacitance calculated?
The total capacitance is the sum of the individual capacitances: $C_{total} = C_1 + C_2$.
In a parallel resistor network, which resistor conducts the highest current and why?
In a parallel resistor network, which resistor conducts the highest current and why?
The resistor with the lowest resistance conducts the highest current because current is inversely proportional to resistance according to Ohm's law.
