Question 22 1 pts An ionic solution contains free charge carriers in a liquid. A potential difference of 31 V is placed between two points (R and S) in the solution. The time taken fora group of charges to move between these two points is 105, and. in this time, the energy of the charges changes by 15 J. What is the average current between R and 5. Give your answer to 3 decimal places. Question 23 1 pts Question 24 1 pts An ionic solution contains free charge carriers in a liquid. A potential difference of 31 V is placed between two points (R and S) in the solution. The time taken for a group of charges to move between these two points is 35, and, in this time, the energy of the charges changes by 14 J. Calculate the power dissipated by the charges. Give your answer to 1 decimal places. The circuit below has a power supply with an EMF of 5 V. What is the total resistance of the circuit? 6.0 $2 '69 '89 '209 119 109
