For calculating the total value of the resistances in a series circuit, we just add all of the values. In this case, it would be 150+60+620 which is 830Ω
For the resistors connected in series the voltage flowing through them is different while the current flowing through them is the same.
The reason for the different voltages flowing through each resistor in series is due to the resistance that each resistor preceding the other poses to the voltage that is passed through it. the formula used for calculating resistance of resistors in series is = R1 + R2 + R3 while for calculating resistance in parallel is = 1/R1 + 1/R2 + 1/R3 = 1/Ret
An array is a collection of similar types of data. For example, if we want to store the names of 100 people then we can create an array of the string type that can store 100 names. String[] array = new String[100];
