Question

# Total resistance is the algebraic sum of the resistance across each resistor in

- Series connection
- Parallel connection
- Both a and b
- None of the above

Hint:

### In a series circuit, all the components are arranged in a single line. In a parallel circuit, all the components are arranged parallel to each other. If more than one resistor is connected in series, the voltage across each resistor is not the same though the current flow is the same throughout the circuit.

## The correct answer is: Series connection

- In a series circuit, all the components are arranged in a single line. In a parallel circuit, all the components are arranged parallel to each other. If more than one resistor is connected in series, the voltage across each resistor is not the same though the current flow is the same throughout the circuit.
- The total resistance of a series circuit is equal to the sum of all the individual resistances in the circuit. Since there is only one path for electron flow in a series circuit, the current is the same magnitude at any point in the circuit.

### Some homes are still heated by hot water boiler furnaces. The components of the system are an oil tank, a furnace, water pipes and radiators. The furnace burns the oil from the storage tank. The heat released is used to heat water which is then pumped to radiators throughout the house. A diagram is shown below.

If all the heat from the combustion was used to heat the water, the system would be 100% efficient. However, some heat is lost in the furnace exhaust and some is lost from the pipes delivering the water to the radiators.

One litre of oil delivers 48 000 kJ of energy. 7 600 kJ are lost to the exhaust, and 900 kJ are lost in transporting the hot water to the radiators. Determine the efficiency of this heating system.
