Friday's class consisted of a closer look at series and parallel circuits. Some examples of calculations include:
-Potential difference is found in the source of the circuit. Can be calculated, V = IR. In a series circuit, individual potential drops add up to the total potential drop. In a parallel circuit, it is constant across the whole circuit.
-In a series circuit, current is constant throughout the entire circuit. In parallel, individual currents are added to equal the total current.
-Resistance in a series circuit can be found by simply adding up all resistances within the circuit. However, in parallel, you must add the reciprocal of each resistor value and solve using the inverse of the total of all the resistance reciprocals.
-Power can be calculated, P = IV, in a series circuit. In parallel, it must be calculated using the formula P = V2/R.
We were also assigned questions 1-5, 13, and 14 on page 488 in the green textbook. The exam review has been handed out so start studying ;)
Christine scribes next.
