15. An electric circuit consists of the following elements : a power supply +; three resistors, RI , R2 and R3 connected in parallel; an ammeter AD that measures the total current intensity in this circuit; an ammeter A that measures the current intensity in resistor R2; a voltmeter V that measures the potential difference (voltage) across the terminals of resistors R3. Draw a diagram of this circuit. 16. Draw a circuit with one pathway, include a fuse, 3 light bulbs, a control (switch). Put an ammeter, a voltmeter for total voltage and a voltmeter for light bulb 2.17. Draw a circuit with three pathways, include 2 resistors and a light bulb, an ammeter for total current, an ammeter for resistor 1 and 2, an ammeter for the light bulb, a fuse for resistor 2, a control for the whole circuit, a control for resistor 1 and a control for resistor 2 and the light bulb
