Geocache Description:

Tervetuloa Simoticin sähköopin jo 2. tunnille. Aiheena tänään teho ja suljettu / avoin virtapiiri.
Jännitelähde oletetaan ideaaliseksi ja liitäntäjohtimien resistansseja ei oteta huomioon.
Valitse oikeat vaihtoehdot tehtävistä ja sijoita saamasi numerot koordinaatteihin.

Johtuen muuttuneesta loppupurkin paikasta, loppunatteja olen joutunut korjaamaan hieman.
Kaava: N 62 AB.E (F-3) (G-1) ja E 029 CD.H (I+2) (J+4)

Welcome to Simotic’s 2. lesson on electricity/electric circuits. Today’s topic is open and close circuit. Battery is ideal and wiring resistances can be neglected. Choose the right alternatives and place the numbers in the coordinates. Go to the cache and log your name in the log book. Log your visit on this site.

Resistors, voltage sources and lamps are of the same value in all circuits. Wiring resistances can be neglected.

5. In which circuit does the lamp glow the brightest?

6. Does the lamp glow changes, when swich of under the lamp opened?

7. When swich between BC is open ... voltage between AB is ...
