  TYPES OF CONNECTIONS: Electric components can be connected in two ways SERIES:   When negative terminal of first component is connected to positive terminal of second component, negative terminal of second component is connected to positive terminal of third component and so on, then the components are said to be connected in series. PARALLEL:   when the positive terminals of all the components are connected to one end and the negative terminals of all the components are connected to another end, then the components are said to be connected in parallel. HOW TO FIND EQUIVALENT RESISTANCE OF COMBINATION OF RESISTORS CONNECTED IN SERIES AND PARALLEL? RESISTORS CONNECTED IN SERIES: In series connection of resistors there is only one path for the flow of current in the circuit. Hence, the current in the circuit is equal to i. But potential difference varies depending upon the resistance of a resistor. According to Ohm’s law, Potential difference across R 1 is , V 1 = iR 1 Potential dif
