Two resistors connected in series have an equivalent resistance of 698.1 Ohm. When they are connected in parallel, their equivalent resistance is 159.9 Ohm. Find the resistance of each resistor. Ohm (small resistance) Ohm (large resistance).
Draw a circuit with a resistance(R=V/I) of 1500 ohms, but you only have access to 1 resistor of 1000 ohm. Hint: use exactly 3 resistors. Use wires, switches, battery, voltmeter, and ammeter, regular resistors of 10 ohms. You can change your resistor value. Do this by using equivalent resistance equations for both series and parallel.
only choose mcq Four resistors, A: 25 ohm, B: 50 ohm, C: 10 ohm and D: 80 ohm are connected in series. A battery of 10 V is applied across the combination. If current is passed through the combination for one hour, heat generated is minimum for which resistor? A. C B. A C. D D. B
You have three identical resistors that you can connect in various ways. Which of the following is NOT a possible value of the equivalent resistance of the three-resistor combinations? 2R/3 O RI3 0 3R O 3R/2 You have five identical resistors. How should they be wired in order to have the minimum possible effective resistance? O Two in series, three in parallel O Three in series, two in parallel O All in series O All in parallel
Three 12-Ohm resistors are set up in parallel. What is the resistance of the single equivalent resistor that would take their place? -4 Ohm -12 Ohm -36 Ohm -None. The method of equivalent resistors can only be applied to two resistors at a time, never three or more.
You have a 10 ohm resistor connected in series with an ammeter. The voltage applied to the whole circuit is 1.2 volts. At the same time you have a voltmeter connected across the 10 ohm resistor and voltmeter reads 0.9 volts. The circuit draws a total of 0.5 amps. Can you determine resistance of the ammeter?
Could you please answer this question
Thanks
