I have this circuit problem, The Resistance is not given yet the Current is 10A and Voltage is 220V
my professor told me that A is the only series, A's value could be = to 3. D to Y is 1 over ? and B to C is also 1 over ? it's really hard but here's the picture link of the circuit.

A voltmeter with internal resistance of 20 kQ (kilo ohms) is connected directly across a resistor (short shunt) and an ammeter is connected in series. The ammeter reads 4 mA (milliamps) and the voltmeter reads 24 Volts.
a) Calculate the resistor value from these readings
b) What is the true value of the resistor
c) What is the percentage error using this method

J.J. and G.P. Thomson, father and son, both performed experiments with beam of electrons. In 1897, J.J. Thomson deduced electrons are particles with definite value of e/m. In 1927, G.P. Thomson deduced that electrons behave like wave. In J.J. Thomson experiment,electrons with kinetic energy 200 eV passed through a pair of plates of 2cm separation. Explain why J.J. Thomson show no evidence for wave like behavior of electrons.

why we cannot decrease the range of an ammeter
Electric Circuits
if electrons are moving from left to right in a space and positive charges from right to left and they meet at a cross section and for every electron there is a positive charge so they totally neutralizes at the cross section ...i want to know that current at the cross section would be zero ?...,it not at any other place

Four Capacitors are connected in Series. They have capacities of 2.2uF, 3.3uF, 4.7uF and 5.6uF. The Series combination is connected to a 200 Volt DC supply. Determine:
a) The total charge
b) The charge across each capacitor
c) the voltage across each capacitor
* Thank you very much in advance if this can be answered. Will help me understand more*

An F1car going into a corner accelerates by -10m/s/s to reduce its velocity by 31m/s. How long before the corner did the driver start breaking? Show method and formula please.
