e. Suitch. 29.4 Draw a simple circuit diegram to illustrate how she should set up the apparatus in order to 29.5 Describe in point form how she should go about doing her investigation and what readings she should take at each step. The following results were recorded in her investigation: No. of resistors in parallel Current strength (A) \begin{tabular}{l|l} \hline 2 & 0,40 \\ \hline 3 & 0,55 \\ \hline 4 & 0,80 \end{tabular} 29.6 Plot a graph of 'current strength' versus 'number of resistors in parallel'. 29.7 What can you deduce from the shape of the graph about the relationship between the number of parallel resistors and the current strength in the circuit?

Figure $27-27$ shows a circuit of four resistors that are con- nected to a larger circuit. The graph below the circuit shows the electric potential $V(x)$ as a function of position $x$ along the lower branch of the circuit, through resistor $4 ;$ the potential $V_{A}$ is $12.0 \mathrm{~V}$. The graph above the circuit shows the electric potential $V(x)$ versus position $x$ along the upper branch of the circuit, through resistors $1,2,$ and $3 ;$ the potential differences are $\Delta V_{B}=2.00 \mathrm{~V}$ and $\Delta V_{C}=$ $5.00 \mathrm{~V}$. Resistor 3 has a resistance of $200 \Omega$. What is the resistance of (a) resistor 1 and (b) resistor $2 ?$
Figure $27-27$ shows a circuit of four resistors that are connected to a larger circuit. The graph below the circuit shows the electric potential $V(x)$ as a function of position $x$ along the lower branch of the circuit, through resistor 4 ; the potential $V_{A}$ is 12.0 $\mathrm{V}$ . The graph above the circuit shows the electric potential $V(x)$ versus position $x$ along the upper branch of the circuit, through resistors $1,2,$ and $3 ;$ the potential differences are $\Delta V_{B}=2.00 \mathrm{V}$ and $\Delta V_{C}=5.00 \mathrm{V} .$ Resistor 3 has a resistance of 200$\Omega .$ What is the resistance of (a) resistor 1 and (b) resistor 2?
