For the first experiment , the error percentage and coded do not match except for three resistors which are within the coded tolerance value of 5%. For equal resistors placed in series, we have to multiply the resistance of one resistor with the number of resistors placed in series. For equal resistors placed in parallel, we have to divide the resistance of on resistor by the number of resistors placed in parallel. In a series circuit with equal resistances, voltage is distribute equally to all the resistors respectively. In a parallel circuit with equal resistances, the voltage remains the same across each resistor as each branch of the circuit gets the same amount of voltage from the power source. In a series circuit with equal resistance, current remains the same throughout each resistor. However, in parallel, current gets equally distriubuted throughout the circuit.
