PSC1501 Portfolio. 100% CORRECT questions, answers, workings and explanations. Whatsapp +25479 093 7672 for assistance.EXPERIMENT 1 : Step 1 : What happens if an electric circuit does not have a resistor ? if there is no resistance, short circuit is connected across an dc source, infinite current will flow as I=V/R, and R=0. Practically, if you connect a wire directly across a battery, it will start heating. Resistance of short wire is in the range of Ohms which is very less as compare to re...
