How to find total resistance and total current in diagram posted
In the electric circuit diagram shown, possible locations of an ammeter and a voltmeter are indicated by circles 1, 2, 3, and 4. Where should an ammeter be located to correctly measure the total current and where should a voltmeter be located to correctly measure the total voltage? * ammeter at 1 and voltmeter at 4 ammeter at 3 and voltmeter at 4 ammeter at 2 and voltmeter at 3 ammeter at 1 and voltmeter at 2 3
QUESTION 1 What is the current read by the ammeter in the circuit below? Let R1 = 1 kiloohm, R2 = 2 kiloohm, R3 = 3 kiloohm, and the emf of the ideal source is 5 volts. Input R1, R2, and R3 for resistors Ri, R2, and R3 respectively. Input E for the emf E. Use context clues to figure out if you need to input a numerical value, variable, word, etc. All numerical answers should be in three significant figures. R1 R2 R3 E First we calculate the current across each resistor. From Ohm's law, we arrive at a general formula for current: | = Plugging in values, the current across the resistor R1 is equal to: (Please note that the current is in milliamperes) mA
Predict the relative brightness of the bulbs in the circuit below, from brightest to dimmest. Assume all bulbs are identical. A B + D highest lowest
You hook up the circuit shown to the right.a) Write a voltage equation that states how the voltage drops across the bulbs relate to the voltage gain across the battery . Use this equation along with Ohm's law for each bulb to determine the current flowing through the bulbs (& battery).b) Determine the voltage across each bulb.c) In a series circuit with bulbs of different resistances, is a bulb with higher resistance likely to be brighter or dimmer than a bulb with a smaller resistance? Discuss this with your group.d) Calculate the power dissipated by each light bulb.e) Calculate the power provided by the battery. Why was this predictable?f) How does each of the following change if a fourth round bulb is added in series? (you may want to look back over how your answers to (a-c) would change) Current Voltage drop across each bulb Brightness of each bulb g) What happens if one bulb burns out?
Consider the circuit below (picture attached) How would you add a resistor with a resistance of 7.00 Ω to the circuit so that the current through the 3.0 Ω resistor is maximized? (This is already answered but I believe this correlates with part b. For this part the new resistor must be in parallel with the 4 ohm resistor) By how much does the current through 3.0 Ω resistor increase when you do what was descibed above? (Must be in units of ampheres please.)
Please I prefer typing instead on writing on paper. Thank you.
Can you please help me solve this.. 4 resistors are connected as shown in the figure. The total current passing through the circuit is 10A, R1 has a resistance of 3 ohms, the voltage across R2 and R4 are 12V and 30V respectively and the current passing through R3 is 1.5A. Determine the total voltage and total resistance of the circuit shown and all other unknowns. *Pls refer from the figure attached* Solve for: (a) Total voltage (b) Resistance of R4 (c) Voltage across R1 •Pls answer with complete and detailed solution (3 DECIMAL PLACES all final answers with correct units) •Sketch an illustration/diagram with labels (this is a must; for a better understanding) Thank you I will give your answer a LIKE for helping me...
