a resistance of 6 ohm is connected in series with another resistance of 4 ohm connected across a battery of 20v . find net resistance,total current,and potential difference across each resistance
Answers
☞ Net Resistance is 10Ω, Current = 2 A
☞ PD across the 6Ω resistor is 12 V & accross the 4Ω resistor is 8 V

Question 3
Unlike parallel connection in a series connection the voltage varies but the current remains constant,so to find the pd across the resistors we shall use the Ohm's law (V=IR)
