The maximum current in an ac circuit is related to the rms current by:
where
is the rms current and
is the maximum current.
If we re-arrange the formula and we use
, we can find the value of the maximum current:
Explanation:
causes hallucinations
causes lung cancer eg cigarettes
causes bad breath
damages the nervous system eg cocaine
Answer:
A compass can detect a magnetic field and show its direction. Iron filings can show the shape of a magnetic field. A gaussmeter can detect a field and indicate its strength.
Explanation:
Explanation:
The free fall acceleration is:
F = ma
20 N = (0.50 kg) a
a = 40 m/s²
The mass of Planet X is:
F = GMm / r²
20 N = (6.67×10⁻¹¹ Nm²/kg²) M (0.50 kg) / (4.0×10⁶ m)²
M = 9.6×10²⁴ kg
Answer:
D
Explanation:
calculate effective resistance of the resistors
= 80 + 120
= 200
overall resistance = 48 ohms
so overall current flowing through circuit
I = V / R
I = 12 / 200
I = 0.06 A
since circuit is in series, current is same at every point so...
potential difference across 80 = R x I
= 80 x 0.06
answer is potential difference = 4.8 V
