In the integral circuit of operational amplifier, a resistor is connected in parallel with the capacitor. What is the function of this circuit? The positive phase input terminal of the integral circuit of the operational amplifier is grounded, the input voltage VI is connected to the reverse phase input terminal through the resistance, the capacitor section is connected to the reverse phase input terminal, and the output V0 is connected to one end. What is the function of this circuit?

The ideal integrator does not need parallel connection of this resistor. The actual integrator will inevitably have bias voltage because of the operational amplifier. Although the bias voltage is very low, it will charge and discharge the capacitor. After a long time, the capacitor will be saturated

A resistor and a capacitor are connected to the power supply in parallel. The teacher said that when the circuit is stable, it is equivalent to an open circuit, that is, there is no current passing through,
The voltage indication is the voltage of parallel resistance. Why? If the voltage at both ends of the capacitor is enough to electrify people, which one will be electrified if people touch one end of the electric container with both hands or touch both ends of it with both hands?
What's the principle of electrocution?

After the capacitor and resistor are connected to the power supply in parallel, there will still be current after stability! Measuring the voltage at both ends of the capacitor is measuring the voltage at both ends of the resistor, because they are connected in parallel!
People only touch one electrode of the capacitor, because it can't form a circuit, so they won't get an electric shock
The main cause of electrocution death is that the heart stops beating due to the interference of electric current

Current voltage resistance capacitance
The power source forms the voltage and the voltage forms the current,
AC power distribution line, zero line and ground wire live line has electricity, zero line and ground wire have no electricity, and the power supply in the home is AC
The direct current is divided into positive and negative poles, and the direct current is alternating current. The battery transformed by rectifier is direct current
Resistance is the blocking circuit
Capacitors store electrical energy and release it when necessary
The red pen is positive and the black pen is negative when the circuit of the buzzer measuring point in the digital multimeter is on or off
The above is my knowledge of electricity. There must be some mistakes. I hope you can help me correct them
My current job is related to circuit, and my basic knowledge is 0
Mainly measuring circuit on-off and measuring DC voltage, I hope you can teach me! Thank you very much

Power supply includes voltage source and current source, voltage source is constant, current is determined by load (electrical equipment); current source is constant, voltage is determined by load. Common power supply is voltage source. 2. Ground wire of alternating current is grounded, equipotential with earth, human station

A light bulb is marked with "220V 40W". When it is connected to a 110V circuit, its actual power is

The bulb is marked "220v40w"
Its resistance R = u & # 178 / P = 220 * 220 / 40 = 1210 Ω
On the circuit of 110V, the power P is real = u & # / r = 10W
