physicsbhelp said:Well for part a) i did 12V=115*I and for I i got 9.583 Amps and that came wrong.
A circuit is a closed loop or pathway through which electricity can flow. It typically consists of a power source, wires, and various components such as resistors, capacitors, and switches.
In a series circuit, all of the components are connected one after another in a single loop. In a parallel circuit, the components are connected in separate branches, allowing multiple pathways for electricity to flow.
In a series circuit, the total resistance is equal to the sum of all individual resistances. In a parallel circuit, the total resistance is calculated using the formula 1/Rt = 1/R1 + 1/R2 + 1/R3 + ..., where Rt is the total resistance and R1, R2, R3, etc. are the individual resistances.
AC (alternating current) circuits have electricity that flows in both directions, constantly changing its polarity. DC (direct current) circuits have electricity that flows in only one direction, maintaining a constant polarity.
First, check all connections to make sure they are secure. Then, use a multimeter to test the voltage and resistance at various points in the circuit. If there is an open or short circuit, check the components for damage and replace as needed.
