Description
"The Laws of Voltage in Series and Parallel Circuits" Voltage Resistance PPT Courseware 5
Review questions:
1. What are the rules of current in series circuits?
The current in a series circuit is equal everywhere
Formula: I=I1=I2
2. What are the rules of current in parallel circuits?
In a parallel circuit, the trunk current is equal to the sum of the branch currents.
Formula: I=I1+I2
1. Voltage rules of series circuits
Ask a question:
What is the relationship between the voltage of each part of the circuit in a series circuit and the total voltage?
guess:
The total voltage in a series circuit is equal to the sum of the voltages across each part of the circuit.
Analyze the tabular data and draw conclusions:
In a series circuit, the total voltage is equal to the sum of the voltages across each part of the circuit.
Formula: U=U1+U2
Note: In a series circuit, if the lamps are different, the voltages at both ends of the lamps will not be equal;
If the lamps are the same, the voltages at both ends of the lamps are equal.
2. Voltage rules of parallel circuits
Question: What is the relationship between each branch voltage and the main circuit voltage?
Design experiments and draw circuit diagrams
1. Measure L1 voltage U1 and record it in the table
2. Measure L2 voltage U2 and record it in the table
3. Measure the total voltage U3 and record it in the table
Analyze the tabular data and draw conclusions:
In a parallel circuit, the voltages at both ends of each branch are equal and equal to the total parallel voltage (power supply voltage).
Formula: U=U1=U2
In the above experiment, what are the experimental errors?
1. There is an error in the reading
2. The voltmeter itself has errors.
3. The status of the circuit is different during measurement (for example, the quality of the contact is different)
True or False
1. If the voltage of two light bulbs is equal, they are connected in parallel.
2. If two light bulbs are connected in parallel, the voltages must be equal.
The power supply voltage is 6V, close switch S,
(1) It is found that only one light is on and the voltmeter indicates 0V, then the possible fault is ()
(2) If you close switch S and find that both lights are off and the voltmeter shows 0V, the possible fault is ()
(3) If you close switch S and find that neither light is on and the voltmeter indicates 6V, the possible fault is ()
A. L1 short circuit B. L2 short circuit
C. L1 is open circuit D. L2 is open circuit
In the circuit shown in the figure, a, b, c, and d are four terminals. After closing the switch S, the bulb L does not light up. If a voltmeter is connected between b and d, and the switch S is closed, the voltmeter will display clearly. number; if the ammeter is connected between b and c, no matter whether the switch S is closed or opened, the ammeter will clearly display the number, and the bulb L will light up. Then the fault must be ( )
A. Bulb L is open circuit B. Bulb L is short circuit
C. Resistor R is short-circuited D. Resistor R is open-circuited
