What are the details of briefly explain the scope of digital system design?

1. Three capacitors with individual capacitances of 2 μF, 5 μF, and 10 μF respectively are connected in series with a 12V battery. What are the total capacitance and total charge in the network? 2. Same capacitors in number 1 connected in a parallel. If the combined charge in the network is 50 μC, what are the total voltage and total capacitance in the network?

A copper wire has a resistance of 𝟏𝟓. 𝟎Ω at a temperature of 14℃. After a

current passes through the windings, the resistance rose to 𝟏𝟐. 𝟓Ω. To what

temperature was the wire heated?

if a 6 volt battery of external resistance 0.5ohms connected to 3 resistors of values 3 ohms,4 ohms,5 ohms.calculate the current in each resistor,the potential difference across the 3ohm resistor and across the parallel resistors.

The capacitors have values C1= 2.0 uf and C2= 4.0 uF, C3=5.0 uF C4= 7.0 uF and the potential difference across the battery is 9.0 V. Assume that the capacitors are connected in parallel

What is the capacitance of a parallel plate capacitor with metal plates, each of area 1.00m², separated by 2.00mm? What charge is stored in this capacitor if a voltage of 3.00×10³V is applied to it?

1.The potential energy of a certain system of two charges increases as the charges are moved farther apart.What does this tell us about the sign of the charges?why?

2.Show that volt per meter is the same as newton per coulomb.

3.A student said"electric potential is always proportional to potential energy,why bother with the concept of potential at all?How would you respond?

1.How would you define membrane potential?

2.What are the factors that could affect the ion movement?

3.If the membrane allows only positive charges to get through it,what happens to the concentration of both sides of the membrane?

4.From what you have learned in Biology,why is membrane potential essential among plants and animals?

The plates of a parallel – plate capacitor uses a disk with a radius of 10mm. The separation distance between the plates is 100 nm and between the plates is a sheet of mica. What is the capacitance of the capacitor?
