2023 - May/June - Paper 1 - Question 8

No memo is currently available

Or

Option 2

Part 1

\mathrm{R}=\frac{\mathrm{V}}{\mathrm{I}}

2=\frac{V}{1,5}

V=3V

Part 2

5=\frac{\mathrm{V}}{1,5}

\mathrm{V}=7,5\mathrm{~V}

Part 3

V_{\mathrm{T}}=\mathrm{V}_1+\mathrm{V}_2

=3+7,5

=10,5\mathrm{~V}

Or

Option 3

Ratio of R

3:7

Ratio of I

7:3

I=1,5\times\frac73=3,5\mathrm{~A}

V=IR

=(3,5)(3)

=10,5\mathrm{~V}
