8) If the resistance in an electrical circuit is held constant, the amount of current flowing through the 8) circuit is directly
Len [333]

Answer:

C) 80 milliamperes

Step-by-step explanation:

The amount of current flowing through a circuit is directly proportional to the amount of voltage applied across the circuit. The relation between current(I) and voltage(V) can be expressed as:

I \propto V\\\\I = \frac{1}{R}V

Here, \frac{1}{R} is the proportionality constant. It is given that, when voltage is 2 volts, 40 milliamperes(40 \times 10^{-3} amperes) current flow through the circuit. Using these  values we can find the value of proportionality constant. i.e.

40 \times 10^{-3}=\frac{1}{R} \times 2\\\\ \frac{1}{R}=20 \times 10^{-3}

Using this value, we can establish the relation between I and V as:

I = 20 \times 10^{-3} \times V

Now, we need to calculate value current (I) if voltage is equal to 4 volts. Substituting V = 4 in above equation, we get:

I = 20 \times 10^{-3} \times 4\\\\ I = 80 \times 10^{-3}

Thus, the value of current will be 80 milliamperes

Find the value of abc-def<br> (I need work shown)
makkiz [27]

Answer:

x = 2.5 cm

Step-by-step explanation:

In Similarity triangles, the ratio of corresponding sides of the triangles are in same.

       \sf \dfrac{AC}{BC}=\dfrac{DF}{EF}\\\\\\\dfrac{x}{2}=\dfrac{11.5}{9.2}\\\\\\x = \dfrac{11.5}{9.2}*2\\\\x = 2.5 \ cm
