Helping me the night before EVERY exam? This guys is my goat
Thank you soo much for teaching me so farr!!!
keep it up bro
Potential Difference (Voltage) in Series: The total potential difference from the power source is shared between the individual components. The sum of the voltages across each component equals the total voltage of the source (1:08-1:41).
Current in Series: The current is the same at all points in a series circuit because there is only one path for the charge to flow (2:11-2:16).
Total Resistance in Series: The total resistance is the sum of the resistances of each individual component (2:48-2:55).
Ohm's Law: The relationship used to calculate current or potential difference based on the circuit's total resistance and the current flowing through it (2:36-2:45).
Voltage-Resistance Relationship: In a series circuit, components with a higher resistance will have a larger share of the total potential difference (5:31-5:49).
While parallel circuits have more than one loop and are in branches which are paths for the currents to flow.
