A resistor is connected to a 36v power supply. An ammeter measures a current of 2.0 A going through it. Determine the resistance
m_a_m_a [10]

R = 18 ohms

Explanation:

Given:

V = 36 volts

I = 2.0 A

R = ?

Use Ohm's law to solve for the resistance:

V = IR

or

R = V/I

= (36 volts)/(2.0 A)

= 18 ohms

A certain part of a computer chip has a length of 1.5 micrometers. How many meters is this ?
Alchen [17]

When you're working with units of measure, "micro" almost always means "millionth", or 1 x 10⁻⁶ .  And that's exactly the case in this example.

"1.5 micrometer" = 1.5 millionths of a meter, or <em>1.5 x  10⁻⁶ meter.</em>

6 An infinite non-conducting sheet has a surface charge density o = 5.80pC/m². (a) How
Anit [1.1K]

a. Work done = 2. 0648 Joules

b. Electrical potential, V = 4. 03 × 10^10 volts

<h3>How to determine the parameters</h3>

a. Work done = force × distance

Force = density × acceleration due to gravity

Force = 5. 80 × 10

Force = 58 Newton

We have that distance = 3. 56cm = 0. 0356 m

Work done = 58 × 0. 0356

Work done = 2. 0648 Joules

b. The formula for electric potential is given thus,

Electric potential, V = k\frac{q}{r}

r = 0. 0356m

k = Coulomb's constant = 8.98*10^9kg⋅m3⋅s−4⋅A−2.

q= 1.60x10^-¹C

substitute into the formula

Electric potential, V = 8. 98 × 10^9 × \frac{1. 6 * 10^-^-1}{0. 0356}

Electric potential, V = 8. 98 * 10^9 × 4. 494

Electric potential, V = 4. 03 * 10^1^0 volts
